An improved shift optical system for a camera which is adapted to be responsive to input received from devices external to the system. An anti-vibration optical system, constituting the shift optical system, is provided so as to be movable on a plane perpendicular to the optical axis of the anti-vibration optical system by a driver. The action of the driver is controlled by a control device which is responsive to input from either an anti-vibration system or an external device. The anti-vibration system of the camera is provided with an image blur detector, which outputs the amount of vibration experienced by the camera, and a compensation amount calculator which outputs a signal to the control device indicative of where the anti-vibration optical system must be placed in order to compensate for vibrations. In order to interface with the external equipment, the control device is connected to a coordinate converter which receives information via a communication device connected to the external equipment. The coordinate converter allows the use of external equipment having a coordinate system that is either of a different scale or skewed from that coordinate system the control device. In operation, the control device accepts and acts upon information from either the anti-vibration system or the external equipment. The external equipment can be, for example, a test device which measures the responsiveness of the anti-vibration optical system over its entire range of movement. Further, the external equipment can be a pattern generating device which directs the anti-vibration optical system to move in a preset sequence to create a pattern of light on a photograph.
